Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a silver halide photographic light-sensitive material, and more particularly to a silver halide photographic light-sensitive material capable of improving the effective sensitivity in under-photographing and the image quality in under-photographing. The present invention relates to a silver halide photographic light-sensitive material capable of reducing print level fluctuation and improving productivity.

2. Description of the Related Art In recent years, photosensitive materials having a sensitivity higher than the normal sensitivity of 100 have been put on the market one after another due to advances in photosensitive material technology for general photography. This is because the camera is compact and a zoom lens with a long focal length is used.
Even though the aperture value (brightness) of the lens itself is small, shooting with a high-speed shutter is required when shooting a moving subject such as a sports photo. This is because it is becoming more and more necessary for ordinary consumers to be less likely to become. However, when these high-sensitivity photosensitive materials are used, a sensitivity of 100
The number of underscenes is larger than that of photography using the photosensitive material described above, and in recent years, it is becoming a problem that it greatly affects factors that lower productivity in printing in the market.

[0003] This is because when the film is underprinted with a negative film, the quality of the actual printed image is higher than the density of the main object, and the expression of the negative density is not sufficient on the shadow side. When the overall density is increased, the overall density is similarly high, that is, darker.On the other hand, when the overall density is decreased, the density of the subject becomes lighter, and the printed image is not tight and cannot be seen. This is because the print density range is narrow and it is difficult to print.

[0004] The occurrence of these under photography occurs indoors,
In addition to the use of a dark lens or a dark lens such as a zoom lens, it is also likely to occur in a case generally called backlight shooting such as "a bright state such as a sky and the subject is slightly darker than that". . In such backlight shooting, the consumer who actually took the picture did not intend to shoot in the dark, but for some reason the finished print was like under photography, and the photographer's recognition and completion The results of a questionnaire survey revealed that there was a large difference in quality, especially in the market, where the problem was likely to be large.

The sensitivity at the time of printing is generally called an effective sensitivity, and the effective sensitivity in a color negative film-color paper system is usually the IS of a color negative film.
It is a well-known fact that although there is some correlation with the sensitivity specified by the O standard (hereinafter sometimes abbreviated as ISO sensitivity), it cannot be simply related.

In order to improve the ISO sensitivity of a color negative film, the sensitivity of a silver halide emulsion largely depends on the size of silver halide crystals. Therefore, the sensitivity is improved by using a silver halide emulsion having a large grain size. It can be easily and technically known, and is generally reported and reported in the literature.

However, in practice, when such a large grain size silver halide emulsion is used, the ISO sensitivity is high, so that the effective sensitivity when printing is slightly increased.
The effective sensitivity was not so effective even if these were improved too much, and the graininess in the image was coarse due to the large particles used, especially when the print magnification such as panorama size was large, the printed image was rough. The problem was that they provided prints that were hard to see in the actual market.

Further, with the advance of technology, a one-channel printer equipped with a scanner having a higher yield in printing is becoming mainstream. This one-channel type printer (hereinafter sometimes abbreviated as 1ch) can scan negative images more finely by using a CCD camera (image scanning) than before, and it is suitable for pattern analysis in each scene. Exposure control can be performed. However, despite the progress of these devices, the actual printing yield in the market cannot be improved as expected, and in order to increase the yield, it is actually shipped to the market with a certain level of quality, It is the fact that it is returning to.

The yield during printing decreases as the number of reprints increases, and decreases due to an increase in the time required for finishing. Causes of the actual re-printing include variations in the characteristics of the photosensitive material due to storability, and variations in the color temperature due to variations in color temperature due to shooting in various scenes, resulting in an undesired print color (print level). No. Further, similarly, the print density may be undesirably finished due to the difference in luminance between the main subject and the background and the area ratio in the scene.

As described above, although the yield has been slightly improved by recent printer technology, it has not been improved as much as expected, and at present, improvement is still required.

As a result of investigating various printers and photosensitive materials to find out the cause, it was found that as a cause of the print level fluctuation, the fluctuation on the under side was the largest, and the fluctuation on the over side was the second largest.

[0012] Even if the density balance of the characteristic curve of the density-light amount of the photosensitive material is simply changed from under to over as described in the known literature relating to photography, the printing is actually performed. Level fluctuations are caused by color temperature fluctuations (e.g., sunny, cloudy, shade,
It has been found that the true cause is that the variation of the leg gradation of the light-sensitive material greatly affects the light intensity of the light-sensitive material.

Next, with respect to the density fluctuation at the time of finishing, in an actual scene, the luminance region (light amount region in a photographed image) is as wide as about 3.5 or more. Because the area other than the main subject uses various light ranges from under to over, and the area occupied by the main subject in the image differs depending on the consumer and on a case-by-case basis. You have to rely on control with lower accuracy than calculation. Moreover, the hardness (hereinafter referred to as γ) of the tone reproduction of the original image in the photosensitive material using the conventional technique is used.
However, the average γ when viewed from the printer is different from the actual γ even if the scene is shot with proper exposure because it is not stable in these wide brightness ranges.
As a result, it was found that the conditions of the exposure time were inaccurate and it was difficult to obtain an appropriate density, or that the condition of the human being who operated the apparatus required judgment and the yield was reduced.

On the other hand, in addition to the above-mentioned 135-mm wide photographic film material of the conventional 35 mm width, a IX240 type photographic film having a smaller image area and a 25 mm width (ADVANCED PHOTO SYSTEM) is used.
M, which may be abbreviated as APS in the future) can record information at the time of photographing on the magnetic layer on the back side of the photographic film itself, and has recently been used widely.

When these films are used, the above-mentioned 1
Unlike the 35-type standard angle of view (vertical: horizontal = 2: 3), the standard angle of view of HDTV (9:16) is 13
Compared to the five types, it is horizontally long, and the area of the subject in the actual angle of view is small. Generally, the exposure condition at the time of photographing is determined by calculating an appropriate exposure condition as a whole from the area of a subject and the exposure of the subject in the scene area to be automatically photographed by the camera. For these APSs,
It was found from the analysis of the camera that under photography by backlight as described above is more likely to occur as compared with the 35 type, and a complaint problem is more likely to occur. In these APSs, 1
It has been found that exposure control during printing as described above becomes more inaccurate than that of the 35 type, and as a result, print level fluctuations and density fluctuations are more likely to occur. There is a need to improve the characteristics of light-sensitive materials.

Further, in the print of a panorama or the like in these APSs, since the photographing area of the negative itself is smaller than that of the 135 type negative, the print is enlarged and printed at a print magnification of about 1.4 times. It was more conspicuous than the type, and it was also found that the overall image quality in the underscene was inferior.

In the current market, underscenes account for about 20% as a proportion. However, the overall image quality of the underscene is inferior to the remaining 80% of the normal and overscenes, and improvement in the image quality of the underscene is desired. It is widely known in the general and literature that sharpness and graininess affect the overall image quality (eg, "Basics of photographic engineering (silver photography): Corona Publishing").
Unlike the normal scene, the overall image quality in the underscene cannot be simply explained by these sharpness and granularity, but it is a proposition how to achieve the image quality improvement efficiently for many years, and a method is desired. ing.

[0018]

As described above, there are various documents and known examples for improving the effective sensitivity. However, when the ISO sensitivity is increased in connection with the granularity, the granularity deteriorates. It did not efficiently improve the effective sensitivity to improve print productivity in the market or reduce the problem of complaints.Moreover, when trying to solve graininess together, large amounts of expensive silver halide were used. It has to be used and has a cost burden. In addition, poor desilvering is liable to occur in the bleaching step of the color negative development step, so that the graininess is rather deteriorated and cannot be solved.

Accordingly, it is an object of the present invention to provide a silver halide photographic light-sensitive material capable of improving print productivity in underscenes and scenes having different color temperatures and solving the problem of the backlight scene.

(21) The silver halide photographic material as described in any one of (9) to (19) above, wherein the photographic sensitivity is 200.

Hereinafter, the present invention will be described in detail.

First, as a result of analyzing the claim problem of the backlight scene, the effective sensitivity at this time is mainly ΔD (G) of the present invention of the green photosensitive layer, which is a contrast difference on the negative in a certain light amount region. This greatly affects the contrast difference of green density: ΔD (G) within the above-mentioned range with respect to the display sensitivity: S (usually corresponding to ISO sensitivity), thereby greatly reducing the problem of the backlight scene complaint. I found that I could do it.

Next, regarding the print productivity in the underscene, the scene distribution in the market, the analysis of the same scene, and the reflection density on the used paper at the time of finishing the preferable color paper were simulated. . As a result, in order to increase productivity, in particular, we found that problems were large in scenes such as under-flash strobes and raised issues. It has been found that the difference in the light source distribution of the sun and the effective sensitivity is mainly affected by the contrast difference in the subject, especially the flesh color of the person. As a result of the analysis, unlike the commonly-known ratio of the visibility of the human eye, green: red = 1: 0.7, the effect of the strobe is green: red = approximately 1: 1. As a result of examining the density region on the negative to be improved from the fact that it was found to be easy to print on paper at the time of printing, the effective sensitivity in this case was not only green sensitive layer but also red sensitive layer. Both of the active layers have an effect, and the contrast difference ΔD (GR) obtained from the green density and the red density in a certain light source distribution falls within the above-mentioned range with respect to the display sensitivity: S, so that a large under level is obtained. It was found that print productivity in a scene could be improved.

Next, regarding the overall image quality, as described above, it is said that the sharpness and the graininess affect the overall image quality. Couldn't.

The overall image quality of the underscene is calculated by calculating the sensory evaluation value of the image quality from the reflection density of the print, the sensory evaluation value of the granularity, and the human visual sensitivity. Since the effect of the color reproduction performance on the quality of the image quality is small, the effect of the sharpness is not so much affected. Therefore, the image quality value Q uniquely determined from the contrast of the green density: CT _G and the granularity: PG _G
(G) could express human sensory evaluation values. As a result, in the present invention, the quality value of an outdoor underscene due to backlight or the like is expressed by a contrast and a hyperbolic approximation with a graininess factor. In order to further improve the contrast, it was possible to clearly determine whether the method of improving the contrast was the shortest method or whether the method was granular, and the overall image quality could be improved efficiently.

Also, in a scene in which a human is the main subject in the flash photography, the reproduction of the skin and the graininess have the same effect, and the photographic quality on the under side during the flash photography is green due to human visibility. of red density contrast not only the concentration: CT _R, graininess: PG _R image quality quality value Q also taken into consideration
(GR) could express human sensory evaluation values.
As a result, in the present invention, the quality value of the underscene at the time of flash photography is expressed by the approximate expression of the hyperbola with the contrast of green and red densities and the graininess as a factor. In order to further improve the overall image quality, it is possible to clearly determine whether improving the contrast of green or red density is the shortest method, or whether it is granular of green or red density, and improving the overall image quality efficiently I was able to.

When S is less than 200 to 400, ΔD (G), which is a defined contrast difference (density difference), is preferably 0.55 to 0.60, more preferably 0.56 to 0.60.
When the ratio is 0.58 and exceeds 0.60, the effective sensitivity is high and preferable, but tone reproduction may be too hard depending on the color paper at the time of printing. When S is less than 400 to 800, it is preferably 0.48 to 0.55, more preferably 0.50 to 0.52, and when it exceeds 0.55, the effective sensitivity is high and preferable, but depending on the color paper at the time of printing, Tone reproduction may be too hard. Further, ΔD (G
R) is preferably 0,2 when S is less than 200-400.
51 to 0.57, more preferably 0.53 to 0.55
If it exceeds 0.57, tone reproduction may be too hard depending on the color paper at the time of printing. S is 4
When it is less than 00 to 800, preferably 0.44 to 0.5
If it is 0, more preferably 0.46 to 0.48, and if it exceeds 0.50, tone reproduction may be too hard depending on the color paper at the time of printing.

When S is 200 or more and less than 400, Q (G) is 8 or more, preferably 10 or more.

Q when S is 200 or more and less than 400
(GR) is 7 or more, preferably 9 or more.

Q when S is 400 or more and less than 800
(G) is 6 or more, preferably 8 or more.

Q when S is 400 or more and less than 800
(GR) is 5 or more, preferably 7 or more.

The display sensitivity S referred to in the present invention is a well-known 13
5, cartridges, patrones, or built-in containers, such as IX240 type, that incorporate the photographic film,
There are various names, but the sensitivity of the light-sensitive material read from the numerical value following the ISO shown on the outside of the container, or the numerical value described in hexadecimal consisting of the high level and the low level described there. When the photographic light-sensitive material is finally used, it means a numerical value of the sensitivity of the photographic light-sensitive material displayed when the photographic light-sensitive material is built in a camera.

In general, a silver halide photographic light-sensitive material is represented by a density curve corresponding to light energy in a combination of a high-speed layer, a medium-speed layer, and a low-speed layer. A slight improvement can be achieved by increasing the sensitivity of the silver halide contained in the upper layer (high-sensitivity layer), but not only that, but also by adjusting the sensitivity of the silver halide contained in the middle layer (intermediate layer). Can be achieved by adjusting the sensitivity of the medium-speed layer so as to contribute on the high-density side of the density-exposure characteristic curve in the high-speed layer, or by adjusting the silver amount of the medium-speed layer.

Similarly, ΔD (R) can be adjusted by appropriately adjusting the upper and middle layers of the red-sensitive layer.
By adjusting the above-mentioned ΔD (G) and ΔD (R), ΔD (GR) of the present invention can be obtained, and an improvement in the effective sensitivity under the flash scene can be achieved.

Next, Q (G) of the present invention is a hyperbolic function of green density contrast: CT _G and granularity: RMS _G , and the desired Q (G) is adjusted by appropriately adjusting CT _G and RMS _G. Can be achieved. In other words, it is calculated from the function of Q (G) of the present invention how much CT _G and RMS _G need to be further improved as means for achieving the target value of the total image quality.
The required ΔD (G) and RMS (G) are estimated by back calculation, and ΔD (G) can be achieved by appropriately combining the above-described methods. For RMS (G),
In addition to using silver halide particles having a small particle size, or appropriately selecting the type of development inhibitor-releasing coupler (DIR coupler), the amount of the DIR coupler is adjusted to change the number of coloring points of the dye cloud during development. be able to.

However, in order to improve ΔD (G), the particle size increases and the graininess deteriorates. Also, RMS (G)
It is necessary to reduce the particle size in order to improve
In view of the fact that the more the R coupler is used, the more the ISO sensitivity is reduced, the interaction between the equations 4, 5, and 6 of the present invention is recognized, and the shortest inventive effect from the present situation is obtained. A silver halide photographic light-sensitive material having excellent overall image quality in underscene can be obtained.

In the same manner as described above, regarding the overall image quality of an underscene during flash photography, the interaction between them is recognized from the relations of the expressions 7 to 10 and 11 of the present invention, and the shortest invention effect from the present situation is obtained. Thus, it is possible to obtain a silver halide photosensitive material of the present invention which is excellent in overall image quality in an underscene during flash photography.

Even if the density balance from the under to the proper exposure is simply changed uniformly as in the known literature and known examples in order to improve the productivity during printing, the color temperature is still low in the evening. In the case and in the case of a strobe light having a high color temperature in which the short wavelength side is not cut, no significant improvement was observed, and the print level fluctuation proposed in the present invention could not be reduced. No improvement effect could be obtained.

Therefore, in the present invention, the distribution of the amount of light in an image in an actual scene due to the difference in color temperature is investigated.
The preferred density-light amount characteristic curve and the photosensitive material characteristic for solving the problem of the present invention were analyzed.

First, a description will be given of print level fluctuation when the color temperature is low. It was found that the sensitivity of the blue light-sensitive layer and the red light-sensitive layer greatly fluctuated, and that the balance between the blue light-sensitive layer and the green light-sensitive layer was significantly lost during proper exposure. These are not improved even if the density balance is simply adjusted as is known in the art, and the coordinates on the density-exposure characteristic curve of the light amount value back calculated using the calculation formula used in the ISO standard when the sensitivity is S. It is found that when Δ is the ISO sensitivity point, ΔγR-ISO of red density is improved at 0.15 or less. If the ΔγR-ISO is 0.15 or less, the effect of the present invention can be obtained, but it is preferably 0.10 or less.

Next, a description will be given of print level fluctuation when the color temperature is high. It was found that the sensitivity of the blue light-sensitive layer and the red light-sensitive layer greatly fluctuated, and the balance between the red light-sensitive layer and the green light-sensitive layer at the time of proper exposure was largely lost. These are not improved even if the density balance is simply adjusted as is known in the art, and the coordinates on the density-exposure characteristic curve of the light amount value back calculated using the calculation formula used in the ISO standard when the sensitivity is S. It has been found that the gradation factor of blue and green density has an effect when is defined as the ISO sensitivity point. However, it has been found that, in practice, human luminous efficiency is smaller for blue than for green, so that ΔγG-ISO of green density is improved at 0.15 or less. ΔγG-ISO is 0.15
The effect of the present invention can be obtained as long as the content is not more than 0.10, but is preferably not more than 0.10.

It is to be noted that γ0 is preferably 0.50 or more for green density and 0.45 or more for red density in view of the hardness of the shadow gradation of the print.

In other words, in order to stabilize the change in color temperature with respect to the change in color temperature regardless of whether the change is low or high, in particular, both the red and green densities ΔγG-ISO and ΔγR-ISO are 0.15 or less. Is effective, and surprisingly, when both of these are satisfied, the print level fluctuation and the density fluctuation at the time of printing can be greatly reduced at a color temperature of 5500 ° K. ΔγG-ISO, ΔγR-
If both ISO and 0.15 or less, the print level fluctuation,
The effect of the present invention of reducing the density fluctuation and further improving the skin color reproduction can be obtained, but is preferably 0.10 or less.

Also, when the color temperature is high, by setting the difference ΔγGG between the maximum value γMAX and the minimum value γMIN of the differential gradient of green density to 0.10 or less, the print level fluctuation and the density fluctuation can be greatly improved. Was. Preferably, the density difference at green density (not an absolute value) and the density difference at red density (not an absolute value) have the same sign. Here, the differential gradient refers to the amount of change in the slope that changes the logarithm of the exposure amount on the exposure-density characteristic curve in steps of 0.1. That is, the point in the difference in exposure amount 0.1 x ₁ and x ₂
And the corresponding densities are y ₁ and y ₂ , the differential gradient at this point is y ₂ −y ₁ / x ₂ −x ₁ . Therefore, 10 × (y ₂ −y ₁ ) is the differential gradient of each point.

On the other hand, when the color temperature is low, by setting the difference ΔγRR between the maximum value γMAX and the minimum value γMIN of the differential density of red density to 0.20 or less, the density fluctuation can be greatly improved simultaneously with the print level fluctuation. Was.

Further, it has been found that ΔγGG is 0.10 or less and ΔγRR is 0.20 or less in order to greatly improve the density fluctuation simultaneously with the print level fluctuation with respect to the color temperature change in each scene. Even more surprisingly, when sharpness is evaluated when these are satisfied, the color blur of the green and red photosensitive layers due to the difference in human visibility is less likely to occur in high frequency components, and the overall sharpness is improved. I understood. Preferably, both ΔγGG and ΔγRR are 0.10 or less.

Next, from the result of the image analysis, when the color temperature is high, the maximum value γMAX and the minimum value γ of the differential gradation of green density are determined.
It was found that by setting the MIN difference ΔγGG to 0.10 or less, it is possible to greatly improve the density fluctuation simultaneously with the print level fluctuation.

On the other hand, when the color temperature is low, the difference ΔγRR between the maximum value γMAX and the minimum value γMIN of the differential density of red density is set to 0.20 or less, and it is found that the density variation can be greatly improved simultaneously with the print level variation. Was.

I in the density-exposure characteristic curve at green and red densities
The slope of the line connecting the point D1 of the density +0.60 to the point of SO sensitivity D0 is preferably 0.40 to 0.80, and particularly preferably 0.55 to 0.70. If it exceeds 0.80, tone reproduction may be too hard depending on the color paper at the time of printing.

The sensitivity referred to in the present invention is a well-known 135, IX
There are various names, such as cartridges, patrones, or built-in containers that contain the photographic film, such as 240 type, etc., but the numerical value following ISO shown on the outside of the container, or the high level described therein,
It may be the sensitivity of a light-sensitive material read from a numerical value described in hexadecimal notation consisting of a low level, and finally, when the silver halide photographic light-sensitive material is used, it is displayed when it is built in a camera. Of the silver halide photographic light-sensitive material.

In general, a silver halide photographic material is represented by a density curve corresponding to light energy in a combination of a high-speed layer, a medium-speed layer and a low-speed layer. In order to produce a photosensitive material that satisfies the above characteristics, first, Δγ
G-ISO and ΔγR-ISO can be slightly improved by increasing the sensitivity of silver halide contained in the upper layer (high-sensitivity layer) of the green and red light-sensitive layers, but not only that, but also the middle layer (intermediate layer). Can be achieved by adjusting the sensitivity of the silver halide contained in and adjusting the sensitivity of the medium-speed layer so as to contribute on the high-density side of the density-exposure characteristic curve in the single-layer high-speed layer, or This can be achieved by adjusting the silver amount of the sensitivity layer. Further, it can be adjusted by appropriately selecting the grain size of the silver halide grains and adjusting the amount of the coupler to enhance the developability.

Similarly, the density difference between the ISO sensitivity point and the line connecting the density point D2 of density +1.20 can be adjusted by appropriately adjusting the upper and middle layers of the green and red photosensitive layers. It can also be adjusted by making the developability of these upper, middle and lower layers closer.

Further, the differences ΔγBB and ΔγRR between the differential gradations
Can be achieved by adjusting the sensitivity and appropriately using the above-described means.

Further, ΔγB / G and ΔγR / G can be achieved by adjusting the silver amount, the grain size, the coupler amount, and the like of the silver halide in the blue-sensitive layer in the same manner as described above.

According to the present invention as described above, a great improvement effect could be obtained in a portion where the exposure range is from under to normal. Further, in the present invention, as a result of earnestly studying the image scanning of the negative image of the device of the 1ch printer and the calculation of the subsequent exposure conditions, and the setup of each channel, the channel setting itself is not performed in the conventional device instead of fine control, that is, In the 1ch printer, there is no problem if the photosensitive material characteristics are under to normal, normal to over, and the density balance is different in each of the two regions, even if the density balance is stable only in each of the regions. It has been found that it is necessary to stabilize not only the density balance but also the gradation hardness in the under region to the over region specified in the exposure region. In other words, in a 1ch printer, even if only the density balance is stable for re-estimating the characteristics of the photosensitive material from image scanning and performing appropriate control finely, the negative gradation in the actual scene image is not stable. In the end, when the density of the main subject is calculated, it is assumed that reproduction with the gradation of the output medium (in this case, color paper) is assumed, and since the negative gradation is unstable, the control becomes inaccurate, They did not make full use of the detailed printer functions.

Therefore, as a result of examining the data processing at the time of image scanning of the printer, 256 gray levels are algorithmically used for digital processing and the reproduction area on the output medium is substantially 300 gray levels (color). The human distinctive density area of the paper is about 0.03 to 3.00), and the negative gradation area that affects this is, after all, a difference of about 1.20 when converted to a negative density (color paper). (The hardness of the tone for tone reproduction is about 2.5 in the main density range). Therefore, when the density point of +1.20 with respect to the density point of the ISO sensitivity point similar to the above is D2, D0
A remarkable effect can be obtained when the absolute value of the density difference at the same exposure on the density-exposure characteristic curve on the line connecting D2 and D2 is 0.03 or less.

Next, as a result of analyzing the print level fluctuation and the density fluctuation on the over side, the data processing at the time of the image scanning of the printer is performed in spite of the fact that the algorithm has only 256 gradations due to the digital processing because of the digital processing. On a real film image, there is an under-over / over-ultra-over area in one frame of a scene. Therefore, when an image is scanned, under-ultra and ultra-over information is compressed in an over-scene, and then printed. It was found that the information was used as information for calculating the exposure conditions, and that an error factor in the calculation was caused, and that the print level fluctuation and the density fluctuation during printing became large.

As a result of diligent studies of these improvements, as for the film performance, maintaining a uniform gradation balance from under to over, which is indispensable in the conventional printer control (not the 1ch type), is not enough. Yes, under ~
It has been found that this cannot be achieved unless a specific differential gradient near normal is maintained even on the over side. That is, in a scene at a low color temperature, the sensitivity is set to S, S is 200 or more, and the differential gradations in the exposure range of luminance-2 and luminance + 4 of the density-exposure characteristic curve in green and red densities are γG and γR, respectively. And the maximum value of the quotient γR / γG at that time is γ
(R / G-MAX) and the minimum value is γ (R / G-MI).
When defined as N), a silver halide photographic material having an absolute value of the difference ΔγR / G of 0.15 or less is a level variation + density variation during printing in over-side photography at a low color temperature. Similarly, when printing an over-shooting scene with a high color temperature, the sensitivity is 200 or more, and the respective differentiations in the exposure area of the luminance-2 and the luminance + 4 of the density-exposure characteristic curve in green and blue densities are performed. Let the gradient be γG, γB and the maximum value of the quotient γB / γG at that time be γ
(B / G-MAX) and the minimum value is γ (B / G-MI).
It was found that when the absolute value of the difference ΔγB / G was 0.15 or less, the print level fluctuation and the density fluctuation could be reduced.

Further, as described above, the IX2 having a width of 25 mm
When using 40 type APS photographic film, it is often printed with a 1ch printer as compared with the conventional 135 type, and the area of the main subject in the horizontal angle and the actual angle of view is smaller than the 135 standard angle of view. Because of the small size, the print level fluctuation and density fluctuation during printing are more likely to be inaccurate, but it has been found that by using these techniques of the present invention, the effect of improving these characteristics can be achieved as compared with the conventional 135 type. .

Further, as a result of analysis at sensitivities of 200 to 800, it was found that when the sensitivity is low 200, the print level fluctuation and density fluctuation during printing are more likely to occur due to the gradation fluctuation as described above. However, when these techniques of the present invention are used, a sensitivity of 200 to 400 to 800
It has been found that the improvement effect can be achieved more than less.

The total amount of silver halide contained in the silver halide color light-sensitive material of the present invention is 8.
0 g / m ² or less, preferably 4.5 to 6.5 g /
m ² , and more preferably 4.5 to 6.0 g / m ² .
The amount of silver halide can be determined by a fluorescent X-ray method.

The blue, green, and red densities obtained by storing, exposing, developing, and measuring the densities as described above are plotted with respect to a common logarithm of the amount of exposure to obtain a density-exposure amount characteristic curve.

Next, the ISO sensitivity referred to here is the ISO standard ISO 5800: 1987 (E), JIS K7
614-1981, the light amount calculated backward from the sensitivity calculation equation and the coordinate point on the density-light amount characteristic curve of the photosensitive material at that time. For example, when the sensitivity is 400, S = √2 / Hm. Hm is calculated by substituting the equation S (sensitivity) = 400 of the following equation, and then substituting Hm into the equation logHm = 1/2 (logHg + logHr) to calculate (logHg + logHr).

In the present invention, the ISO sensitivity point D0 is obtained from the characteristic curve as Hg = Hr (the green and red photosensitive layers are regarded as the same and considered as a scale of sensitivity evaluated in the market). In the case of 400, logHg = -2.45 (three digits after the decimal point are truncated).

In the present invention, the non-photosensitive layer adjacent to each of the medium-speed layer and the low-speed layer has a non-diffusion layer which develops substantially the same hue as the diffusion-resistant coupler contained in the medium-speed layer and the low-speed layer.

When the non-photosensitive layer of the present invention contains a diffusion-resistant coupler, the coupling speed is higher than that of the diffusion-resistant coupler contained in the medium-speed layer, which has the highest coupling speed. Equal or less. For further details, see JP-B-62-57023, JP-B-3-000
Nos. 616, 4-012462, 5-000694
Issue.

The emulsion of the silver halide color photographic light-sensitive material of the present invention may be a normal crystal such as cubic, octahedral or tetradecahedral, or a twin having a tabular or columnar twin or an irregular multi-surface. It may be a crystal. Regarding the halogen composition of the grains, silver iodobromide may contain silver chloride.

In the high-sensitivity layer of the present invention, it is particularly preferable to use monodisperse tabular twin grains having a relatively low silver iodide content (hereinafter, referred to as tabular grains).

The tabular grains according to the present invention are particularly preferably those having usually two twin planes parallel to the main plane. The twin plane can be observed with a transmission electron microscope.

The thickness of the tabular grains can be obtained by observing the section using the above-mentioned transmission electron microscope, obtaining the thickness of each grain in the same manner, and performing averaging. The thickness of the tabular grains is preferably from 0.05 to 1.5 μm, more preferably from 0.07 to 0.50 μm.

The tabular grains have an aspect ratio (particle diameter / grain thickness) of 5 or more in 50% or more of the total projected area, and preferably have an aspect ratio of 7 or more in 60% or more of the total projected area. More preferably, 70% or more of the total projected area has an aspect ratio of 9 or more.

The grain size of the tabular grains is represented by the equivalent circle diameter of the projected area of the silver halide grains (the diameter of a circle having the same projected area as the silver halide grains), and is 0.1 to 5.0.
μm is preferred, and more preferably 0.5 to 3.0 μm.

The tabular grains according to the present invention are preferably monodisperse silver halide emulsions.

The tabular grains according to the present invention are preferably emulsions mainly containing silver iodobromide as described above. However, as long as the effects of the present invention are not impaired, silver halide having another composition, for example, Silver chloride can be included. In that case, the silver iodide content on the surface is preferably 1 mol% or more, more preferably 2 to 20 mol%, and particularly preferably 3 to 15 mol%.

The tabular grains according to the present invention preferably have dislocation lines in both the central region and the peripheral region of the main plane. The central region of the main plane of the tabular grains as used herein refers to the thickness of a tabular grain having a radius of 80% of the radius of a circle having the same area as the main plane of the tabular grains and located at a circular portion when the center is shared. Area that has On the other hand, the peripheral region of a tabular grain refers to a region having an area corresponding to an annular region outside the central region, existing around the tabular grain, and having a thickness of the tabular grain.

Examples of a method for introducing dislocation lines into silver halide grains include a method in which an aqueous solution containing iodide ions such as potassium iodide and a water-soluble silver salt solution are added by a double jet, or a method including silver iodide. A method of adding a fine grain emulsion,
A method of adding only a solution containing iodide ions;
Known methods such as a method using an iodide ion releasing agent as described in No. 11781 can be used to form dislocations originating dislocation lines at desired positions. Among these methods, a method of adding a fine grain emulsion containing silver iodide and a method of using an iodide ion releasing agent are particularly preferable.
When an iodide ion releasing agent is used, sodium p-iodoacetamidobenzenesulfonate, 2-iodoethanol, 2-iodoacetamide and the like can be preferably used.

In the present invention, when tabular grains are used, during the step of forming and / or growing the grains,
Metal ions are added using at least one selected from cadmium salts, zinc salts, lead salts, thallium salts, iron salts, rhodium salts, iridium salts, indium salts (including complex salts), and the inside and / or the surface of the particles are added. These metal elements can be contained in the steel.

As a means for forming tabular grains, various methods well known in the art can be used. That is, any combination of the single jet method, the controlled double jet method, the controlled triple jet method, etc. can be used, but in order to obtain advanced monodisperse grains, it is necessary to produce silver halide grains. It is important to control the pAg in the liquid phase to be adjusted according to the growth rate of the silver halide grains. As the pAg value, a range of 7.0 to 12 is used, and preferably 7.5.
~ 11 regions can be used. In determining the addition rate, JP-A Nos. 54-48521 and 58-4
No. 9938 can be referred to.

The step of preparing tabular grains is roughly divided into a nucleation step, a ripening step (nucleus ripening step), and a subsequent growing step. It is also possible to separately grow a previously prepared nuclear emulsion (or seed emulsion). The growth process may include several stages, such as a first growth process and a second growth process. The growth process of tabular grains means all growth processes from the nucleus (or seed) formation to the end of grain growth, and the start of growth refers to the start of the growth process.

In order to form dislocation lines selectively in the central region of the main plane in the tabular grains, it is important to increase the pH in the ripening step after nucleation and to ripen the tabular grains so as to increase the thickness. However, if the pH is too high, the aspect ratio becomes too low, and it is difficult to control the aspect ratio in a subsequent growth step. It also causes unexpected fog deterioration. Therefore, the pH / temperature of the aging step is preferably 7.0 to 11.0 / 40 to 80 ° C, and
5 to 10.0 / 50 to 70C is more preferable.

In order to selectively form dislocation lines in the peripheral region of the tabular grains, an iodine ion source (for example, silver iodide fine particles, iodine ion emitting It is important to increase the pAg in the grain growth after adding the agent to the base particles, but if the pAg is too high, so-called Ostwald ripening proceeds simultaneously with the grain growth, and the monodispersity of the tabular grains deteriorates. Would. Therefore, the pAg for forming the outer peripheral region of the tabular grains in the growth step is preferably from 8 to 12, more preferably from 9.5 to 11. When an iodine ion releasing agent is used as an iodine ion source, dislocation lines can be effectively formed in the outer peripheral region by increasing the amount of iodine ion releasing agent. The amount of the iodide ion releasing agent to be added is preferably 0.5 mol or more per mol of silver halide, more preferably 2 to 5 mol.

The tabular grains may be those obtained by removing unnecessary soluble salts after the growth of the silver halide grains, or may be those in which the soluble salts are still contained.

It is also possible to carry out desalting at any point during silver halide growth, as in the method described in JP-A-60-138538. When the salts are removed, Research Disclosure may be used.
(hereinafter abbreviated as RD) No. 17643 No. II. More specifically, in order to remove the soluble salt from the emulsion after the formation of the precipitate or after the physical ripening, it is possible to use a Noudel washing method performed by gelling gelatin, and inorganic salts, anionic surfactants, A precipitation method (flocculation) using an anionic polymer (eg, polystyrene sulfonic acid) or a gelatin derivative (eg, acylated gelatin, carbamoylated gelatin, etc.) may be used. As a specific example, a method described in JP-A-5-72658 can be preferably used.

The silver halide emulsion can be optically sensitized to a desired wavelength region using a dye known as a sensitizing dye in the photographic industry. The sensitizing dyes may be used alone or in combination of two or more. A dye which has no spectral sensitizing effect by itself together with the sensitizing dye or a compound which does not substantially absorb visible light and which enhances the sensitizing effect of the sensitizing dye is contained in the emulsion. May be.

An antifoggant, a stabilizer and the like can be added to the silver halide grains according to the present invention. It is advantageous to use gelatin as the binder. The emulsion layer and other hydrophilic colloid layers can be hardened,
In addition, a plasticizer and a dispersion (latex) of a water-insoluble or soluble synthetic polymer can be contained.

When the silver halide photographic light-sensitive material of the present invention is used as a silver halide color photographic light-sensitive material, a coupler is used in the emulsion layer. Further, a development accelerator, a developer, a silver halide solvent, a toning agent, a hardening agent, a fogging agent, an antifogging agent, and a coupling with a competing coupler having a color correcting effect and an oxidized form of a developing agent, Compounds that release photographically useful fragments can be used, such as chemical sensitizers, spectral sensitizers, and desensitizers.

In the silver halide photographic light-sensitive material of the present invention,
Auxiliary layers such as a filter layer, an antihalation layer, and an antiirradiation layer can be provided. In these layers and / or the emulsion layers, dyes which flow out of the light-sensitive material or are bleached during the development processing may be contained.

In the silver halide photographic light-sensitive material of the present invention,
Matting agents, slip agents, image stabilizers, formalin scavengers, ultraviolet absorbers, optical brighteners, surfactants, development accelerators and development retarders can be added.

As the support, cellulose triacetate or polyethylene terephthalate film, laminated paper, baryta paper and the like can be used.

[Table 6]

As can be seen from the results in Tables 5 and 6, ΔγG-
With ISO of 0.15 or less, the effect of reducing print level fluctuation is recognized at a high color temperature of the strobe.

Similarly, when ΔγR-ISO is 0.15 or less, the effect of reducing the print level fluctuation is recognized at a low color temperature of 3400 ° K.

Further, it can be seen that when both ΔγG-ISO and ΔγR-ISO are 0.15 or less, the effect of reducing print level fluctuation is further exhibited even at a color temperature of 5500 ° K.
